how can I do this without a GIGANTIC image showing up on the InDesign board? I'm copying a photo from PSD to InDesign and the image shows up on the InDesign board larger than the page, I don't get it? Thank You! Cyndi

It's not a good practice to copy a photo from Photoshop to InDesign. Often such photos are 72 ppi but huge in dimensions as you see. You may also lose quality in the process.

Instead, choose File > Place. If you click the image it will also be very large. But, instead, if you drag the cursor, the proportions will be respected, but you can scale it to the size you want, at least as a starting point.

don’t know what you mean by click, drag the loaded Place gun? Sorry and thank you!

Just so you understand what's going on, if you cut and paste from Photoshop or Place (without clicking and dragging to control the image frame as others have suggested), the image is pasted or placed scaled at 100% of its output size. So if you open the image in Photoshop and check Image>Image Size you can check the image output dimensions. This image would be 18.18 inches in width when placed at 100% in InDesign. I could also uncheck Resample, change the output size to 9 and it would then place at 9 inches on the InDesign page.
